Does anyone in the UK have two old cylinderhead bolts that I could have so I can convert them to guide studs or tell me where I can buy them?
Thanks
If you don’t get any offers for old studs, I normally use plain round bar cut to length.
It doesn’t have to be screwed tightly into the block, just fit well enough that it doesn’t rock about. Then I find the head goes where you want it to and the gaskets stay in place.

God morning,
I have two suggestions,
You can get a yard of 7/16 UNC studding on ebay for about £12.00.
Although I do appreciate that the reduced diameter of an old head bolt makes it a bit easier.
If you have the facilities, you could make them by drilling and tapping the thread part of an old screw and extending it with a smaller diameter piece of studding, which is what I did.

Much better than metal studs is 10mm nylon rod from EBay. Cut to length and use a 7/16” tap on the end to make a thread. No risk of scratching the underside of the head with these unlike using old head bolts or lengths of threaded steel rod
I made my temp studs from brass rod and threaded the end w/ a die. I also cut a screwdriver slot in the opposite end and also put a slight taper on that end too. I like the idea of a plastic stud.

Mrozik,
I am pretty sure I have som old studs if you still need them. I can check tomorrow, I have just had wine with my evening meal and have also opened a beer so don’t think I want to get dirty this evening.

If you use cut off bolts they will be hard to extract. Go the route of threaded rod or just plain 3/8 round stock will get you close enough.

Thanks for everyone for the suggestions - I decided to go for the 3/8 rod solution - cost £3.64 delivered

Something to consider if you ever have major engine work done is to have locating dowels machined into the head and block. That’s what I have. Obviously need a shop that does precision work.
